Last year: Zach Johnson made a 30-foot birdie putt in regulation for a 66 and won the four-hole aggregate playoff over Louis Oosthuizen and Marc Leishman. Jordan Spieth, going for the third leg of the Grand Slam, missed the playoff by one shot.

Last time at Royal Troon: Todd Hamilton got up-and-down from 40 yards away using a hybrid for his fourth straight par to defeat Ernie Els in a four-hole playoff.

Key statistic: Americans have won the claret jug the last six times at Royal Troon.

Noteworthy: Lee Westwood played in the final round with both major champions this year, Danny Willett at the Masters and Dustin Johnson at the U.S. Open.

Quote worthy: "It's like two golf courses. It's blowing out on the front and everything plays real short. Then you turn around and come into a left-to-right wind and you spend the back nine trying to kill it and keep it left." — Jim Furyk on Royal Troon.
